5 GHz near-ground indoor channel measurements and models

摘要

Near-ground wireless channels are becoming increasingly important for a number of applications. In this paper we add to the body of work on this topic, by quantifying small-scale near-ground channel fading characteristics in indoor environments, at 5 GHz. Results for delay spreads, multipath component persistence, and amplitude fading are used to develop models for this channel. As expected, the near-ground channel can yield more dispersion and deeper fading than its counterpart with elevated antennas.
